Features

Output Voltages of 5, 6, 8, 9, 10, 12, 15, 18, 24 Thermal Overload Protection Short Circuit Protection Output Transistor Safe Operating Area Protection General Description The LM78XX series of three terminal positive regulators are available in the TO-220 package and with several ﬁxed output voltages, making them useful in a wide range of applications. Each type employs internal current limiting, thermal shut down and safe operating area pro- tection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as ﬁxed voltage regulators, these devices can be used with external com- ponents to obtain adjustable voltages and currents.

To specify an output voltage, substitute voltage value for “XX.” A common ground is required between the input and the
CI is required if regulator is located an appreciable distance from power supply ﬁlter.
CO improves stability and transient response.
